Dry-season wetlands derived from Landsat archive for NAWRA

Dry-season wetlands data show the average value derived from each season’s maximum number of consecutive days where surface water has been identified during the dry seasons from 1988 to 2016 from Landsat imagery. This dataset was created for the CSIRO Northern Australia Water Resource Assessment (NAWRA) project.
These data are maps of dry-season wetlands derived from the Landsat archive from 1988 to 2016 (i.e. 29 years). The Landsat archive data were extracted from Geoscience Australia’s Surface Reflectance NBAR product available on the National Computing Infrastructure. The method used to derive the surface water maps is described in the NAWRA technical report (Sims et al., 2016). The data are provided as average number (from the 29 years of Landsat data) of the maximum consecutive days of inundation during each dry season. The average number of maximum consecutive days is then converted into shape files: one showing all pixels containing an average value of 50 or more maximum consecutive days of inundation from all the dry seasons; the other showing all pixels containing an average value of 100 or more maximum consecutive days of inundation from all the dry seasons.
